Unfortunately a bit intrusive, being in the top corner of the browser every time I hover over an image (the Chrome Extension shows this after a right click - much less intrusive). Also this extension was leaving random code in text areas and WYSIWYG editors that I was writing content in)

Doesn't seem to work with small image -- which is what I needed it for.

Очень хорошо для тех, кто хочет видеть, что он смотрит, что загружает.
